"Application July-26,1957, Serial No. 674,456

I sclaims. (21. 2-14 Thislinvention relatesto goggles of the. typedesigned to protect the eyes ofithe wearer against dust, dirt and,other. foreign matter, such goggles being used particularlybyindustrial workers .of' various kinds such as in rwelding grinding andsimilar occupations where flying particles present an eye-safety hazard.

A fairly common type of safety goggle of this general class comprises acontinuous generally oblong lens memberand a. frame or supportmemberwhich fits about the periphery of the lens member and is secured theretoor interlocked therewith. The frame or support member extendsrearwardlyfrom; the lens member, and its rear.

edge isr contoured to fit against the faceof the wearer, particularlyagainst the forehead, the cheekbone and. the

- noseportionsofthe face;

Certain. prior art formsof safety goggles of this generalclasscomprise aframemember which extends about the "lens member with an.opening at'thebottom of the frame at apointiwhere the lens is notched'or otherwiseformed-to accommo'date thenose of the wearer. An eX- ample'of safetygoggles of this form is found in Taylor, etal. Patent No. 2,770,807.. Inother formsof this general type-ofsa-fetygogglesthe framemembercomprises a' continuous'loop which 'fitsentirely about theedges of thelens. memberhaving a-reentrant portion in registry withthelowercentralnotchof the lensmember provided to accommodate. the nose ofthe wearer.Both of these general types. of safety goggles have distinct advantages.

I throughout the-nose notchofthe lens may fit better and be. morecomfortable for, certain types of use.

' States P e t i 2,914,770 vPatented Dec. 1, 1959 whereby a softer ormore flexible plastic material may be used for this portionof the frameto rest more easily on the nose of the wearer, it being understood thata relatively more self-sustaining material is required for. the'mainframing portion of the goggles;

.Various modifications and mechanical advantages may be made in thegoggles illustrated and described herein without departing from theprinciples of the present invention. Itis to be understood that theembodimentthus illustrated and described in detail is set forth by wayof example and that the principles of the invention are not limitedthereto or otherwise than as defined-in. the appended claims.

In the drawings: i

Fig, 1 is a general front elevational view of an assembled goggles ofone form of the'present invention;

Fig. 2 is a side; elevational view of the goggles of Fig. 1 with thefront portion shown as a vertical central crosssectional view; Fig.1 3is a fragmentary bottom plan view of the central portion of the gogglesof Fig. l; and

- fits over the edge oflens member 10.

The present invention provides a safety goggle arrangeing member inposition the goggles possess all of the advantages of the continuousloop type of goggle frame but may be manufactured with greater facilityand assembled about the lens with greater ease. Furthermore, thearrangement is such that the separate nose framing portion may beomitted or may be readily removed from y .the goggles as desired. Thisomission or removal may be for any of various reasons, for instance whena mask or inhalator is to be employed which would normally beinterferred with by the nose framing portion of the continuous loop typeof goggle frame.

A further important advantage of the separate nose piece frame memberconstruction of the present invention resides in the fact that itpermits the use of a different material for the nose piece portion ofthe frame In its Fig. 4 is an enlarged fragmentary cross-sectional viewof one ofthe junctures of the two frame portions of the goggles of Fig.1, the view being taken similarly to.

Like'characters of reference denote like parts in the several figures ofthe drawing and, referring more particularly to Fig. 1, a lens member10' of transparent, rela-,

tively stiff, plastic or other material is horizontally ob.- long tocover both of the eyes of the wearer and is notched at its lower centralportion to accommodate the wearers nose, all; as shown in, Fig. 1 and asis generally. known. in the. art. A main frame member 11 extends acrossthe. top and sides of the lens member 10 andterminatesgenerally at thelower part. of the lens member at opposite sides of the nose notchthereof. As shown in Figs. 1 and 4' the lens member 10 is provided witha pair of hook formations 12 for interlockingengagement with the framemember 11 in a manner which.

will presently appear. Y

Therear edge of frame member 11 is contoured irregularly as indicated at13 in Fig. 2 to fit againstv the,

trated-herein, aswill be seen from Figs. 1 and 4, channel formation 14of frame member 11 terminates short ofnthe hook formations 12 of thelens member 10. Beyond the terminus of eachend of channel formation 14-the frame member 11 is slotted as at 16 in. Fig. 4 to fit over thecompanion hook formation 12 of thelens member and the end portions offrame memberll are preferably fianged as at17 to shroud or enclose theassembled hook formation 12 when the frame is in assembled position.

The nose portion framing member is designated 20 and generally forms acontinuation of the main frame member 11, being provided in a similarmanner with a channel formation 21 which fits over the edge of the noseopening notch in the lens member 10. The rear edge portion of noseframing member 20 is contoured as at 23 in Figs. 2 and 3 to more or lessfit and rest upon the nose of the wearer and, as indicated in thepreamble hereto, may be formed of a relatively soft plastic material toprovide a comfortable nose rest portion.

The end portions of nose framing member 20 are notched as at 25 to fitover hook formation 12, being retained in assembled position over suchhook formations by the overlying end portions of the main framing In theform illus- I member 11 as clearly shown in Fig. 4. The lens member ispreferably notched as at 26 to accommodate such end portions of the noseportion framing member 20.

Thus in assembly the nose portion framing member 20 is merely placedin'position with its notches 25 assembl'ed ove'r the hook formations 12of lens member and the-main framing member 11 is then assembled in thesame manner as in the above-identified Taylor, et al. patent, suchassembly of the main framing member automatically retaining the noseportion framing member in proper assembled position. If the nose portionframing member is not desired it is merely omitted in this assemblyoperation. If desired, the nose portion framing member 20 may becemented or otherwise attached to the companion end of the main framingmember in a more'or less permanent manner, either at one end or atbothends. While this does not permit ready omission of the nose portionframing member, it still affords certain manufacturing advantages andpermits the use of a different material for molding the nose portionframing member than the material of the main frame member.

A head band 30 is attached to opposite sides of the main framing member11 in an adjustable manner as shown in Fig. 2 and as is known in theart.
